The Recoil only has 350 or 500 psi, if I remember. Depending on the tool you're using, you'll need 1000 psi or more. I say so because if you're using a rotary jet tool, your psi could be about 1/2 if there are two jets. On the other hand, if you're using a rotary brush, the psi doesn't matter. I won't go near any job without at least 1200 psi with my rotary jet wand.
A unit with a vacuum that delivers a mere 100 cfm can handle the water most pumps deliver, so a powerful vacuum isn't required unless you're planning to use a hose over 50'.
External pumps with 1200+ psi can be purchased at hardware stores, so using one of those in combination with almost any portable is the cheapest solution if you need high psi. If you do use high pressure, auto fill and dump is hard to do without.
